[Importance of echocardiographic study in assessing left ventricular contractility in ischemic heart disease].

Echocardiographic examination was conducted in 41 patients with ischemic heart disease. The results were compared with the findings of ventriculography. It was established that echocardiography reveals the presence of zones of asynergia in the left ventricular myocardium in the diaphragmatic and anterolateral areas in a high percentage of cases, but it is practically impossible to determine affection of the apical segments by this method.
